Examples of skip or skipTo functions?

[Anonymous]

I have been attempting to use the skip and skipTo functions to move to a particular location in an mp3 file but the files always start back at the beginning.

A snippet of the code is below:

MP3player.playTrack(i-firstPin);

result = MP3player.skip(track[i].currentPosition);

The result is zero.

I am running on a bareconductive touchboard.

Any ideas on how to debug this?

Hi Dean,

This is probably too late to help you but I fixed the problem for myself.

I think there is a problem with the maths in SFEMP3Shield.cpp

track.seekSet(((timecode * Mp3ReadWRAM(para_byteRate))/1000) + start_of_music)

I think that timecode * Mp3ReadWRAM(para_byteRate) is causing an overflow in the intermediate calculation i.e. before the division by 1000.  When I display the calculated values that is what appears to be happening.

I have now changed the arithmetic to remove the divide by 1000. I supply a jump defined in seconds not milliseconds and I can now jump to anywhere in the file
